I used 2 different methods on my '07 Charger. On the huge Dealer badge on the trunk lid, I used the heat gun and started pulling it away from the trunk lid, as the adhesive got warm enough. Then, when I removed the door molding, I just went along the top edge of the molding squirting some of that Goo Gone on the top side of the molding and going along the lower edge of the molding with a rag, to catch any Goo Gone that came on through. In both cases though, I used the Goo Gone to clean up the area AFTER the Badge and the molding was gone. That video was very informative too.
